Ich glaube nicht, dass es eine Möglichkeit gibt, das zu tun, was Sie wollen (zeigen Sie den PasswordItem-Editor bei der Visualisierung der ListGrid-Felder an). Wie Sie bereits herausgefunden haben, funktioniert setEditorCustomizer nur im Bearbeitungsmodus.
Aber Sie können die Feldwerte maskieren. Hier ist, wie es zu tun:
// very important for not having to set all fields all over again
// when the target field is customized
listGrid.setUseAllDataSourceFields(true);
// customize the isHidden field to make it respond to changes and
// hide/show the password field accordingly
ListGridField isHidden = new ListGridField("isHiddenFieldName");
isHidden.addChangedHandler(new ChangedHandler() {
@Override
public void onChanged(ChangedEvent event) {
// the name of this field has to match the name of the field you
// want to hide (as defined in your data source descriptor,
// ListGridField definition, etc).
ListGridField passwordField = new ListGridField("passwordFieldName");
if ((Boolean) event.getValue() == true) {
passwordField.setCellFormatter(new CellFormatter() {
@Override
public String format(Object value, ListGridRecord record, int rowNum, int colNum) {
return ((String) value).replaceAll(".", "*");
}
});
}
// you need to re-add here the isHidden field for the ChangeHandler to
// be present when recreating the ListGrid
listGrid.setFields(isHidden, passwordField);
listGrid.markForRedraw();
}
});
// add the customized field to the listGrid, so that we can have the
// desired ChangeHandler for the isHidden field
listGrid.setFields(isHidden);
